Zusammenfassung 1. Das Streupulver (Delicia-Ratron-Streupulver) hat sich bis jetzt als ein recht brauchbares Hausrattenmittel gezeigt. wenn es in Verbindung mit geeigneten Ködern den Hausratten einverleibt werden kann.Eine Pulver- oder Köderscheu besteht nicht, dagegen kann von einer anlockenden Wirkung gesprochen werden. Die wiederholte Annahme anderer Giftköder durch Hausratten ist bekannt, diese Köder finden noch bessere Annahme. Bei der Auslage von Brotscheiben kann die unangenehme Verschmutzung der Auslegestelle durch das Pulver durch ein loses Einwickeln der Scheiben in Zeitungspapier verhütet werden.2. Der Zeitpunkt für die Anlage von Schüttungen war günstig. Von Anfang Oktober bis Ende März des nächsten Jahres haben die Hausratten die Winterquartiere bezogen. Ein gewisser, aber nicht durchschlagender Erfolg kann diesen Schüttungen zugesprochen werden, doch steht der Erfolg in keinem Verhältnis zum Aufwand an Material und Arbeitszeit.3. Die Ursache des angeblich gesteigerten Lärmes in den Einschüben der Zimmerdecken bedarf noch der Klärung.4. Das Streupulver war für mich ein neues Rattenmittel, dessen Anwendung und Wirkungsbreite ich durch eigene Versuche kennen lernen wollte. Eine solche Versuchsreihe, die Anlage von Schüttungen, die Suche nach geeignetem Ködermaterial konnte recht gut, im Zuge der pausenlosen Schädlingsbekämpfung, die hier eingeführt ist, erfolgen. 相似文献

Background
Bovine paratuberculosis is an incurable chronic granulomatous enteritis caused by Mycobacterium avium subspecies paratuberculosis (MAP). The prevalence of MAP in the Swiss cattle population is hard to estimate, since only a few cases of clinical paratuberculosis are reported to the Swiss Federal Food Safety and Veterinary Office each year.Fecal samples from 1,339 cattle (855 animals from 12 dairy herds, 484 animals from 11 suckling cow herds, all herds with a history of sporadic paratuberculosis) were investigated by culture and real-time polymerase chain reaction (PCR) for shedding of MAP.Results
By culture, MAP was detected in 62 of 445 fecal pools (13.9%), whereas PCR detected MAP in 9 of 445 pools (2.0%). All 186 samples of the 62 culture-positive pools were reanalyzed individually. By culture, MAP was grown from 59 individual samples (31.7%), whereas PCR detected MAP in 12 individual samples (6.5%), all of which came from animals showing symptoms of paratuberculosis during the study. Overall, MAP was detected in 10 out of 12 dairy herds (83.3%) and in 8 out of 11 suckling cow herds (72.7%).Conclusions
There is a serious clinically inapparent MAP reservoir in the Swiss cattle population. PCR cannot replace culture to identify individual MAP shedders but is suitable to identify MAP-infected herds, given that the amount of MAP shed in feces is increasing in diseased animals or in animals in the phase of transition to clinical disease. 相似文献36.

Avian bornaviruses (ABV) are known to be the causative agent of proventricular dilatation disease (PDD) in parrots and their relatives (Psittaciformes). A broad range of ABV genotypes has been detected not only in psittacine birds, but also in other avian species including canary birds (Serinus canaria forma domestica) and Bengalese finches (Lonchura striata f. dom.), which are both members of the order songbirds (Passeriformes).During this study 286 samples collected from captive and wild birds of various passerine species in different parts of Germany were screened for the presence of ABV. Interestingly, only three ABV-positive samples were identified by RT-PCR. They originated from one yellow-winged pytilia (Pytilia hypogrammica) and two black-rumped waxbills (Estrilda troglodytes) from a flock of captive estrildid finches in Saxony. The ABV isolates detected here were only distantly related to ABV isolates found in passerine species in Germany and Japan and form a new genotype tentatively called ABV-EF (for “estrildid finches”). 相似文献

Synchronization of estrus and ovulation are of paramount importance in modern livestock improvement programs. These methods are critical for assisted reproduction technologies, including artificial insemination and embryo transfer, that can increase productivity. In the current study, subcutaneous implants containing norgestomet were placed for long (14 days), medium (9 days), and short (5 days) periods of time in 70 crossbred ewes undergoing fixed-time artificial insemination. The resulting effects on estrus synchronization and conception rates were subsequently evaluated. Among the synchronized ewes, 85.7% (60/70) underwent estrus over a period of 72 h after progestagen treatment ceased. The shortest mean interval between withdrawal of the device and onset of estrus (34.2 ± 8.9 h) was observed in the G14 days of P4 group (p < 0.05). The conception rate of the G14 days of P4 group was statistically higher than that of the other groups (83.3% vs. 60.9% vs. 47.8%; p < 0.05). In conclusion, 14 days of norgestomet treatment produced higher conception rates and a greater number of pregnancies at the beginning of the breeding season. 相似文献

Data on the G.S.I. of adults and appearance of fry indicated a regular lunar spawning cycle of S. rivulatus within a seasonal breeding period. A mass collection technique yielding 5000–7000 fry per day was developed. 相似文献

Models of coccidiosis-monitoring known from literature are described. A suitable alternative of determining the coccidia status in a broiler population is the "modified Johnson-Reid method". This method makes a standardization of diagnostic finding and evaluation possible as well as a differentiated intestinal localization and the determination of coccidia incidence severity. In addition to the microscopic screening of the caecum contents--as described by Johnson-Reid--it appears necessary to take also swabs from parts of the duodenum and jejunum (near the Meckel's diverticulum). Subsequently this method is an important help for veterinarians working with broiler production, for diagnostic institutions as well as producers of anticoccidial agents, especially in regard to its documentation rate and the resulting consequences. In this way other diagnostic efficiency data in broiler production are significantly completed. 相似文献

A cell-based high-throughput screen that assessed the cellular stability of a tumor suppressor protein PDCD4 (Programmed cell death 4) was used to identify a new guanidine-containing marine alkaloid mirabilin K (3), as well as the known compounds mirabilin G (1) and netamine M (2). The structures of these tricyclic guanidine alkaloids were established from extensive spectroscopic analyses. Compounds 1 and 2 inhibited cellular degradation of PDCD4 with EC50 values of 1.8 μg/mL and 2.8 μg/mL, respectively. Mirabilin G (1) and netamine M (2) are the first marine natural products reported to stabilize PDCD4 under tumor promoting conditions. 相似文献
